.Os
.Sh NAME
.Nm zpool Ns Pf - Cm add
.Nd Adds specified virtual devices to a ZFS storage pool
.Sh SYNOPSIS
.Nm
.Cm add
.Op Fl fgLnP
.Oo Fl o Ar property Ns = Ns Ar value Oc
.Ar pool vdev Ns ...
.Sh DESCRIPTION
.Bl -tag -width Ds
.It Xo
.Nm
.Cm add
.Op Fl fgLnP
.Oo Fl o Ar property Ns = Ns Ar value Oc
.Ar pool vdev Ns ...
.Xc
Adds the specified virtual devices to the given pool.
The
.Ar vdev
specification is described in the
.Em Virtual Devices
section of
.Xr zpoolconcepts 8.
The behavior of the
.Fl f
option, and the device checks performed are described in the
.Nm zpool Cm create
subcommand.
.Bl -tag -width Ds
.It Fl f
Forces use of
.Ar vdev Ns s ,
even if they appear in use or specify a conflicting replication level.
Not all devices can be overridden in this manner.
.It Fl g
Display
.Ar vdev ,
GUIDs instead of the normal device names. These GUIDs can be used in place of
device names for the zpool detach/offline/remove/replace commands.
.It Fl L
Display real paths for
.Ar vdev Ns s
resolving all symbolic links. This can be used to look up the current block
device name regardless of the /dev/disk/ path used to open it.
.It Fl n
Displays the configuration that would be used without actually adding the
.Ar vdev Ns s .
The actual pool creation can still fail due to insufficient privileges or
device sharing.
.It Fl P
Display real paths for
.Ar vdev Ns s
instead of only the last component of the path. This can be used in
conjunction with the
.Fl L
flag.
.It Fl o Ar property Ns = Ns Ar value
Sets the given pool properties. See the
.Xr zpoolprops 8
manual page for a list of valid properties that can be set. The only property
supported at the moment is ashift.
